To determine the sensitivity and specificity of CT in depicting bronchial anastomotic complications after lung transplantation.
A retrospective, blinded review of 105 CT scans obtained after single (n = 17) or double (n = 10) lung transplantation in 27 patients was done by two radiologists in consensus. CT images, were analyzed with respect to the status of bronchial anastomoses, with three possible answers given to the readers: normal, dehiscence, or stenosis. CT features were correlated to bronchoscopic and follow-up findings, which were considered as standard of reference.
CT had a 60% sensitivity and 98% specificity for the diagnosis of bronchial dehiscence, and 40% and 99% for the diagnosis of anastomotic stenosis. One case of bronchial disruption was diagnosed on CT scan only and subsequently confirmed by repeated bronchoscopy.
In our study, CT has a low sensitivity but a high specificity in the detection of bronchial anastomotic complications after lung transplantation. However, CT remains useful in some cases, as it can show complications not seen bronchoscopically.
确定CT在显示肺移植术后支气管吻合口并发症方面的敏感性和特异性。
两位放射科医生对27例患者进行单肺移植（n = 17）或双肺移植（n = 10）后获得的105份CT扫描进行回顾性、盲法分析并达成共识。分析CT图像中支气管吻合口的状况，给阅片者三种可能的答案：正常、裂开或狭窄。将CT特征与支气管镜检查及随访结果相关联，后者被视为参考标准。
CT诊断支气管裂开的敏感性为60%，特异性为98%；诊断吻合口狭窄的敏感性和特异性分别为40%和99%。仅在CT扫描上诊断出1例支气管破裂，随后经反复支气管镜检查得以证实。
在我们的研究中，CT在检测肺移植术后支气管吻合口并发症方面敏感性较低但特异性较高。然而，CT在某些情况下仍有用处，因为它能显示支气管镜检查未发现的并发症。
